Hello everyone

Did you ever use order's shortcut? It is one of cool client feature that help you to manage vehicles order. If you looking for how to become more quick, I think you should give it a try.
To find this, you can go to settings and simply type "shortcut" and you would see something like the image below.
Now, since OpenTTD 12.x update, somehow it looks a little weird. But don't worry. To understand how it works, you have to know which action given by each value.
1 - Full load any cargo
2 - Transfer and leave empty
3 - Unload and (take cargo or leave empty)
4 - No unloading and wait for any full load
5 - Transfer and leave empty (and replace the last order)
6 - No loading
My recommendation is
Ctrl + left click at value 1
Alt + left click at value 3
Ctrl + Alt + left click at value 2
Notes:
Ctrl + left click should at value 1, since that was the default control
Any shortcuts with shift were not work (I think its a bug)
You could ignore
do nothing and click on each options to see the value.
I leave this here for future of myself, and hope you find it useful thank you
